registry

问题 I have been trying to find a way to "defragment" the registry on my Windows machine. Firstly, does this make sense? Any benefits in doing this?

(I might have to write the new file and then boot into another OS/disk before I can overwrite the original... but I am willing

问题 Where is a reliable registry key to find install location of Excel 2007? 回答1: How about: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\X.0\Common\InstallRoot] which contains a key named 'Path' with the installation directory of that version of Office. This is consistent for Excel 8.0 through 12.0. If you want to look for a specific product, use Excel, Word, Access, etc., in place of Common.

问题 How can one check to see if the SQL Server Client driver is installed? And is it also possible to determine the version? 回答1: Go to->Run->cmd->type regedit.exe and you see the registry under the ODBC folder: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ ODBC Drivers\SQL Server I also find a complete answer about this issue, (based on MySQL, but basically is the same thing). Edit later: according to your comment you have installed the 2005 version of SQL Server: HKEY_LOCAL_MACHINE\SOFTWARE
